TEM image of representative condensates of linear DNA condensed by spermine (no HU present). TEM image of representative condensates produced under identical conditions as that shown in A, except in the presence of 100 nM HU. Scale bar is 100 nm. Relative rod populations plotted as a function of HU concentration for linear DNA condensed by spermine. Samples were 5 µM DNA bp, 15 µM spermine chloride, 0.33 × TE (pH 7.8), 15 mM NaCl and indicated concentrations of HU dimer.
